A surprisingly high number of city citizens in China suffer from poor health and many die at an early age. Poor health with no sign of any identified disease, a condition known in China as "sub health," is on the rise. Sub health is marked by general weakness, low energy levels and a poor immune system. A survey held in 16 cities with over 1 million population showed high proportions of urban Chinese have been suffering sub health problems. The numbers are particularly high in Beijing, Shanghai and Guangzhou, with 75.31, 73.49, and 73.41 percent respectively of residents in poor health, the survey showed. The problem happens mostly among senior and middle-level managers, clerks and other white-collar workers with high education levels, said the website of the Red Cross Society of China. "The sub health condition, found in most cases among groups of people with a high educational level, will have bad effects on China's long-term development and progress if not dealt timely and properly," the website warned. A survey by the Chinese Academy of Sciences shows that the average life of Chinese intellectuals is 58 years, 10 years lower than the nation's average. This early death phenomenon may be increasing. Among Chinese people with high education in the 25-59 age group, the death rate for women is as high as 10.4 per cent. For men it is even higher: 16.5 percent. A report published by the China Sub Health Academic Seminar said the country's health is going through a transitional period and many long-term diseases have taken the place of infectious diseases such as SARS and flu as the main cause of death. "Bad working habits, poor disease prevention knowledge, not enough governmental investment and lack of health education are the main reasons," said Yang Xiaoduo, a healthcare expert with a local health association, who said China should race against time seeking measures to solve the sub health problem. According to the text, which of the following is NOT true? A) Chinese people especially the city citizens are suffering from sub health problem. B) Infectious diseases used to be the main cause of death across China. C) Sub health problem will do damage to our country's development. D) Now more and more people realize the importance to stop sub health.

For most teenagers, swapping   an old mobile phone with a friend for the latest album or movie ticket might be considered a good trade.But 17-year-old Steven Ortiz set his sights a little higher, and -- after a series of swaps -- is now driving himself to school in a Porsche.The youngster started exchanging items two years ago after a schoolmate gave him an unwanted phone.Through a series of online swaps, Steven worked his way up through newer phones, laptop computers, and street bikes before landing the prized Porsche.  Steven developed a love for online trading long before taking up the swaps that led to the Porsche.As a young teenager, he would buy his friends' unwanted mobile phones for around PS20, clean them up and sell them over the Internet for three times that amount.  His father, Esteban Ortiz, said Steven was also useful to have around when the family needed something like a new washing machine, as he would use his nose for a bargain to pick up somebody's discarded appliance for next to nothing and fix it up cheaply."I think this is teaching him something.I want him to go to college, and make something of his life.He is learning the value of things, responsibility and negotiation skills."  Steven got his first car at 15, but he was too young to drive, so he traded for a golf cart before moving back into cars when he got his license a year ago.Steven said swapping the Bronco, worth about PS10,000 at the time, for the Porsche was actually a trade down because the car was valued at PS6,000.Another downside is the running costs.He must pay PS100 every time the Porsche needs an oil change, and $1,000 for a routine service.  Steven, however, still has some way to go before matching the achievement of Canadian Kyle MacDonald, who became famous four years ago for turning a single red paperclip   into a two-storey farmhouse through a series of trade. What does Steven's father think of him?   _  . A) He took on heavy responsibilities at a young age. B) He could always get real bargains. C) He has made some progress and is promising. D) He has spent too much time bargaining.

There are stories about two U.S . presidents,Andrew Jackson and Martin Van Buren,which attempt to explain the American English term OK.We don't know if either story is true,but they are both interesting. The first explanation is based on the fact that President Jackson had very little education.In fact,he had difficulty reading and writing.When important papers came to Jackson,he tried to read them and then had his assistants explain what they said.If he approved of a paper, he would write "all correct"on it.The problem was that he didn't know how to spell.So what he really wrote was "ol korekt".After a while,he shortened that term to "OK". The second explanation is based on the place where President Van Buren was born,Kinderhook,New York.Van Buren's friends organized a club to help him become President .They called the club the Old Kinderhook Club,and anyone who supported Van Buren was called"OK". .According to the second story, the term "OK" was first used   _ A) by Van Buren B) in a presidential election C) to organize the Old Kinderhook Club D) by the members of the "ld Kinderhook Club"
